PSU for this system, Any ideas?

[alexp999]

Hi,
I'm gonna be building the following system for my dad:
XFX 680i LT Mobo
Intel Q6600 g0 @ 3Ghz with Freezer 7 Pro
2x Asus GeForce 8800GTS 640mb in SLI
Creative Sound Blaster Audigy SE 24-Bit
2x Seagate Barracuda 160GB 8mb SATA2 in Raid 0
1x 140mm Blue LED Fan, 3x 120mm Fan.

Now we have all the parts except the PSU. Any ideas? I found this one:

Let me know what you think,

Thanks.

We'd like to buy from this site:
www.ebuyer.com
Seems to me that the OCZ I mentioned above is a bargain at £55 compared to the others in that price range, the £60 ones are only 500w ones.

Let me know what you think,

Thanks.

You need at least an 700W PSU to be on the safe and stable side.

Thanks, so how about this one then:

The 700w version,

Thanks.

Thats fine sure...However IF you can buy the 850W version, if not the 700W version should suffice

Really? You think that 850w would be better? how come If you don't mind me asking. I checked a review site since:
http://www.legionhardware.com/document.php?id=656
I appreciate as they have said a 600w might be a bit near its limits but if you compare the system on legion hardware to the one I'm building above...
I'm still learning tho, any help appreciated,

Thanks.

Well the 8800GTS in SLI is the reason you should reach 700W , not to mention that if you want to OC your system and you will also OC your GTS so the more you can get the better and do try to get a good brand with good rails for better stability. I would tell you to consider ENERMAX PSUs but you would have to spend at least 150$ for a good one.

K, how much power do they take then? it only has one pci-e connctor on the GFx card. Only thing is I'm in UK. Struggling to find good PSU's. OCZ seems to be the best value for money over here.

Thanks.

edit:
Anyone UK based now a good place to get them from?

Thanks.

 

[HellasVagabond]

You could use www.kelkoo.co.uk to find stuff online in the UK......
Just try to get a 700W PSU and you will be fine

Thanks, think I will stick with getting a 700w. Just did the Extreme PSU calculator which came up with a PSU rating of 547w. So I appreciate that a 600w PSU is too tight. Will get the 700w PSU. Thanks.

Hi,
Just out of interest, what would this be like in comparison to the 700w GameXStream OCZ?

Thanks.

Whoa that's a lot of power... yeah might want 700 watts there...
edit just seen your post. Stay away from Hiper.

 

[HellasVagabond]

Hiper makes nice PSUs almost identical to the OCZ ones in terms of performance. In any case this is a fine PSU

 

[hat]

no they don't hellas. Ask POS PC... I think he's the one with a dead hiper

 

[HellasVagabond]

I had an Dead ENERMAX once..Does that mean ENERMAX doesnt make quality PSUs ? No, it just means that sometimes bad things happen.

 

[alexp999]

K never mind that last one, There is a shop near me which i thought sells the Hiper but they dont have it any more. Has anybody ever heard of silverstone?
What they like?
This is the one they have for sale:
http://www.silverstonetek.com/products/p_contents.php?pno=st75f&area=uk
Its will cost £110 ($220) That good?
Never heard of this company, any info greatly appreciated,

Thanks.

Hiper uses Fujjiyu (or something) capacators, the same the Antec Smartpowers had. We all know how much the smarpowers blew. My smartpower made a high pitched squeal when asked to power a P4 2.8, 2x512MB DDR400, and an XFX 6800XT. I'm just glad it didn't blow up on me.

Silverstone makes good PSUs, they used to make even better back in the old days but since OCZ, ENERMAX and others got into the game their PSUs offer almost the same.
Its a fine PSU...Just get it, its not a car buddy

Well it will cost £82.36 for the OCZ GameXStream 700W
or £109.99 for the Silverstone ST75F 750W (http://www.silverstonetek.com/products/p_contents.php?pno=st75f&area=usa)
Is it worth the extra? Any real difference in the two apart from the Silverstone is modular?

Thanks.

 

[HellasVagabond]

50W more and modular wiring.....Depends....If you will use every available power connector get the OCZ, if not you could use the free space by having less power connectors in your tower.

 

[hat]

If the Silverstone is modular and the OCZ isn't, get the Silverstone unless you have a case capable of hiding a lot of wires, and you've gotta be confident you can hide them too. The silverstone will be a lot easier to manage and silverstones are great.

 

[alexp999]

K, apart from modular stuff, would you say build quality is better on the Silverstone?

Thanks.

 

[hat]

Silverstone is one of the best PSU makers out there.

 

[gR3iF]

Silverstone...

Get a Corsair or pc power. Watch latest results on Tpu tests. And dont forget that silverstone builds the corsair psu but they are cheaper.

And in the latest tomshardwareguide psu stresstest the silverstone died.

STAY AWAY FROM HIPER! pos_pc and me both have dead psu's from them. His took out the circuit in his house and mine fried my motherboard. I actually ordered the OCZ 700w a couple days ago after reading lots of very solid reviews. PCP&C makes solid units along with seasonic corsair and silverstone.
